中文摘要:

新 1,8-naphthalimide 衍生物在 C-4 位置被 pyridin-4-ol 在哪个代替被准备。这衍生物显示出好冻结性质极的溶剂的那个罐头 gelate 大多数。作为一个 achiral 分子,螺旋状的纤维形态学被观察什么时候复合 gelated 丙酮溶剂。当 D 酒石的酸或 L 酒石的酸的 0.5 eq 被加到胶化时,螺旋状的形态学被改变从对右手的结构左手。这结果被圆形的二色性测量进一步证明。英尺红外实验显示出在 gelator 和酒石的酸之间的分子间的 H 契约的形成。gelator 的 photophysical 性质没在酒石的酸的增加前后有差别;而薄片状的结构被酒石的酸的增加改变。

英文摘要:

A new 1,8-naphthalimide derivative was prepared in which the C-4 position was substituted by pyridin-4-ol. This derivative shows good gelation property that can gelate most of polar solvents. As an achiral molecule, helical fibre morphology was ob- served when the compound gelated acetone solvent. When 0.5 eq of D-tartaric acid or L-tartaric acid was added to the gel, the helical morphology was changed from left-handed to right-handed structure. This result was further proved by circular dichroism measurement. FT-IR experiment showed the formation of intermolecular H-bond between the gelator and tartaric acid. The photophysical properties of gelator had no difference before and after addition of tartaric acid; whereas the lamellar structure was varied by addition of tartaric acid.
