The most parts of thesis as follows:1. Five symmetrical intra-molecular charge transfer oligomeric phenylene vinylene light emitting materials were designed and synthesized using oligomeric phenylene vinylene as a framework.2. The structures of target molecule were characterized by ~1HNMR,~(13)CNMR, IR, MS and element analysis.3. In order to study the influence of the location and numbers of electron-donor and electron-acceptor on their photoelectric performance by changing length of OPV chain, the UV spectra and fluorescence spectra of target compounds has been compared. We have researched into main factors effecting on material emitting red-shift; organic electroluminescence device was prepared using the compound P4. The capability of eletroluminescence was researched.4. The photoelectric properties of P4 was explained by quantum chemical calculation (the Gaussian 98 quantum chemistry program). It is greatly contributed know the whole process of charge transfer to guide the design of red emitters.

Objective To investigate the application of anterolateral thigh fasciocutaneous flap on abdominal chronic ulcer,and provide evidence for its clinical use. Methods From Oct 2005 to Dec 2008,5patients with abdominal ulcer caused by different reasons were repaired with anterolateral thigh fasciocutaneous flap, the flap pedicled with rami descenden of lateral circumflex femoral artery was designed according to the size of abdominal defect,the vessel pedicle was dissociated adequately, the flap was transferred to the abdominal wound under appropriate tension through tunnel, the donor site was sutured directly or repaired with skin-grafting. Results The anterolateral thigh fasciocutaneous flap survived well in all 5 patients,there were no other complication such as skin necrosis.

In this process, the discharge process of single point to point contact is transformed to the process of both point to point contact and the overall surrounding contact of sphere Ni through the self redox reaction, thus making a highly efficient electron transfer process. In this dissertation, the catalytic electrolysis mechanism is discussed. The influence of various parameters (e.g. kind and concentration of catalyst, reaction temperature and electrolysis duration) on electrolysis were investigated.

Certainly have not suffered loss, Li is a former British Hong Kong government is one of Li Ka-shing is indeed business Wizards, in the case of real estate are constantly rising had considered restructuring and the transfer of assets, has bought some foreign quality assets, telecommunications companies such as Germany orange shares, the New Jersey ports, the Panama Canal shares, and Hong Kong Cyberport aggressively into the building, will tentacles stretching the transformation and upgrading of telecommunications, Li Ka-shing is the only person in his fox, and many people are of the view that is Li and the former British Hong Kong government to give them weaving a better future, a beautiful dream, and Tung took office play his body more healthy, more destructive power of the strong characteristics of this beautiful dream hit a smash, this is one is caught, the onlookers-to the real estate collapse of the responsibility of all to Mr Tung who is totally unjustified, Although Mr Tung to the mainland, Beijing has followed some acts are in the eyes of some people, but to objectively evaluate, Dong is a honest kind of person, he is inadvertently let Tianzao point that the arrival and the day is certainly coming, the night time, the more devastating losses, Originally, the intention is that Mr Tung real estate prices trend eased, and then the case now almost Shanghai, prices every quarter on a 20% increase, almost all Hong Kong people have been crazy, and just opened a new development, the stage has long been ranked team to effectively alleviate this situation, the new SAR government changed in the past starvation effect of land supply policy, a substantial increase in the level of land supply in order to stabilize high land prices, while the Yuen Long, New Territories into the new City of mass construction, the expansion of public housing, housing construction plan (equivalent to our low-cost housing, economic applicable housing), if no major accident These measures should ensure that real estate to landing, but nobody thought that 98 years of financial turmoil, Hong Kong dollar devaluation Suoluosiming gambling, but the call foul silent do real estate, stock market doing transactions, the use diversionary tactics tactical let him return home with a full load, although the SAR government have been successfully defend the Hong Kong dollar does not depreciate, but the housing market and stock market watch.
当然也有没受损失的,李嘉诚算一个,前港英政府也算一个,李嘉诚不愧是商界奇才,在房地产不断攀高的情况下就已经考虑资产的转型和转移了,先后购买了一些外国的优质资产,如德国橙电信公司的股份、新泽西的港口、巴拿马运河的股份,并大张旗鼓地投入香港数码港的建设,将触角伸进香港电信的升级改造,李嘉诚做人方面堪称是只老狐狸,很多香港人都认为,是李嘉诚和前港英政府给他们编织一个美好的前程、一个美丽的梦,而小董上台后发挥他那身体越健壮、破坏力越强的特点,将这一美丽的梦击个粉碎,这正可谓是当局者迷、旁观者清,将香港房地产崩溃的责任全部归咎于董建华身上,是完全没有道理的,虽然董建华在靠近大陆、追随北京方面有些行为在港人眼里是过了一些,但客观地评价,董是一个老实厚道的人,他只不过是无意中让那一天早一点到来,而那一天是肯定会到来的,时间越晚,损失越惨重,本来董建华的初衷是希望房地产上涨的趋势有所缓解,当时香港的情形与现在的上海差不多,房价每隔一个季度就上涨20%以上,几乎所有的港人都为之疯狂,新楼盘刚开张,台前早已排起长长的队伍,为有效地缓解这一局面,新上任的特区政府一改以往饥渴效应的土地供应政策,大幅度地增加一级土地的供应,以平抑高昂的地价,同时宣布元朗、新界等新城区进入大规模建设,扩大政府公屋、居屋营建计划(相当于我们的廉租房、经济适用住房),如果没有大的意外,这些措施应该能保证房地产的缓着陆,但谁也没想到,98年的金融风暴,索罗斯明赌港币贬值、暗里却大做不动产、股市空头交易,这一声东击西的战术让他满载而归,虽然特区政府成功地实现了捍卫港币不贬值的目标,但香港的房市、股市从那一刻起,一败涂地。
