ether ting
Examples
- ( 7 ) the effects of crown ethers and soft units on polymers properties were sophisticated
门）冠醚环和柔性间隔基对聚合物的热力学性能和液晶性能的影响是复杂的。 - ( 6 ) conformations of crown rings of polymers were different from those of crown ethers , the two benzene rings of crown in polymers were contorted to each other
（ 6 ）在聚合物中，冠醚环的构象不同于相对应的小分于冠醚环的构象。两个苯环发生了相对扭曲，夹角变大，冠醚环变得舒展。 - The compounds with symmetric structure and different size crown ether rings , 16 and 18 , have higher tm and tj than those of the compounds 17 with the asymmetric structure . the tm and ti of compounds 18 is higher than the compounds 16
含有对称结构和不同大小冠醚环的化合物， 16和18 ，它们的熔点和液晶态的清亮点高于含有不对称冠醚环的化合物17 ，且化合物18的熔点和液晶态的清亮点也高于化合物16的熔点和清亮点。 - Liquid crystal crown ether is a kind of compound , which remains the liquid crystal property when the crown ether ring link or insert to the molecular structure of liquid crystalline compound . it is in fine - order structure and unite its function and character into together . so it is a kind of novel compound with the characterstic of liquid crystal and the selecting of the crown ether
液晶冠醚是一类将冠醚环插入或连接在具有液晶性的分子结构中并保持液晶性质的化合物，这种化合物是一类结构有序且功能特性一体化的体系，它是一类既有液晶特性又有冠醚选择配位功能的新型化合物，它们在分子结构、性能和应用功能等方面都与通常的液晶化合物不同。 - And they are different with the common liquid crystal compound in the molecular structure , property and application function . up to now , people have more interest on the them in the field of transferring signal and information at the molecular level . starting from the molecular design , three novel series of schiff base type liquid crystal crown ethers were synthesized
从分子设计出发，设计并合成了三类新的席夫碱型液晶冠醚化合物，根据分子中冠醚环和木端烷氧基的不同和大小以及化合物的构型将其分为六个系列， 24个化合物。
