Descended from a long line of New England ministers, Emerson, finding himself fettered by even the most liberal ministry of his day, gently yet audaciously stepped down from the pulpit and, with little or no modification in his interests or utterances, became the greatest lay preacher of his time. From

The results show that the as-synthesized chalcone-containing copolymers are a kind of thermosensitive polymer with a lower critic solution temperature and the LCST of the copolymer decreases with the increase of the chalcone content in the copolymer. With the increase of the solvent polarity, both the maximum absorption wavelength and the fluorescence emitting wavelength of the chalcone-containing copolymers redshifts, and the intensity of fluorescence first increases, then decreases, which exhibits solvent polarity sensitive fluorescence properties.

结果表明，侧链查尔酮共聚物是一类具有低临界溶解温度的温敏性聚合物，其LCST温度随着共聚物中查尔酮含量的增加而降低；随着溶剂极性的增加，侧链查尔酮共聚物的紫外-可见最大吸收波长红移，其荧光发光波长红移并且发光强度先增强后降低，具有溶剂极性敏感的荧光特性；同时对比侧链查尔酮共聚物水溶液低温和高温下的荧光，发现低温下几乎无荧光，高温下其荧光得到明显增强，其荧光具有可逆的温度&开/关&特性。
