Described is a polyimide prepared from a diamine containing a spiro or cardo group in a molecule structure, wherein the dimensional stability of the polyimide can be improved at a high temperature, and thus the polyimide can provide a polyimide film useful for a flexible substrate.
Studies on Chemical Modification of Monensin. V. Synthesis, Sodium Ion Permeability, Antibacterial Activity, and Crystal Structure of 7-0-(4-Substituted benzyl)monensins.
7-O-(4-Substituted benzyl)monensins (3a-g) were synthesized from monensin (1), and their lipophilicity, antibacterial activity, and Na+ ion permeability were examined. 7-O-(4-Ethylbenzyl)monensin (3e) showed the largest Na+ ion permeability, but 3c,f,g showed smaller Na+ ion permeability than 7-O-benzylmonensin (2) in spite of higher lipophilicity. An X-ray study of the sodium salt of 3e revealed that
