以4，4′-二苯甲酰氯和2，4-二羟基-4′-烷氧基偶氮苯为单体，通过溶液聚合，合成了一系列新的含T-型二维液晶基元的液晶高分子配体。

The four reaction channels including hydroxyl-type benzaldoxime are endothermic reaction, thermodynamically non-spontaneous process, but the other four reaction channels including ion-type benzaldoxime participation are exothermic reaction and thermodynamically spontaneous process. The latter four reaction channels, which have lower reaction barriers, faster reaction velocities and bigger equilibrium constants than those of the former fours, are the chief reaction channels.

苯甲醛肟以羟基型参与反应的4个反应通道均为吸热反应和热力学非自发过程，它们均具有较高的反应势垒、较慢的反应速率和较小的平衡常数；而以离子型参与反应的四个反应通道均为放热反应和热力学自发过程，它们的反应势垒较低，反应速度较快，平衡常数也较大，故苯甲醛肟应主要以离子型参与反应。

Quinone methides, generated in situ from the reaction of 4-hydroxycoumarin with benzaldehyde, formaldehyde and pentanal, underwent the Diels-Alder reaction with silyl enol ethers to give a series of 3,4-dihydro-2H,5H-pyrano[3,2-c][1]benzopyran derivatives in high yields.
