We have designed and synthesized 9,9'-spirobifluorene-based materials and introduced different functional group at 2,2' and 2,2',7,7' positions of 9,9'-spirobifluorene. All of these obtained materials adopted a bichromophoric system configured orthogonally via a chiral spiro center.

中文摘要以旋环双芴为核心结构，分别在2，2'与2，2'，7，7'位置引入不同基团，设计合成出ㄧ系列具双共轭的材料，两相正交相互独立的共轭链，使分子具光学异构物，可避免分子堆叠，提高热稳定性。

The results of observation on the microstructure of Karelinia caspica, Tamarix stromongolica, Salsola collina. Cheno Dodium glaucum, stipa bangenana show that the nutritional organs of these halophytes present some adaptability structures as follows:(1) sunken stomas, thick cuticle and orderly arrangement of epidermal cell;(2) equilateral leaves with developed palisade tissue, or squama-shaped leaf;(3) well-developed water-storing tissue in stems and leaves;(4) crystal cells, salt glands in most of the leaves and assimilating branches.

通过对花花柴、甘蒙怪柳、猪毛菜、灰绿藜、长芒草五种盐生植物显微结构观察，这五种盐生植物营养器官的形态结构均呈现一定的适应性特征：(1)气孔器下陷，角质层加厚，表皮细胞排列紧密而整齐；(2)多为等面叶，叶片栅栏组织发达，或退化为鳞片状，而具同化枝；(3)茎、叶多为肉质化，贮水组织发达；(4)具有含晶细胞，枝叶具盐腺。
