Isomeric N-(Nitrenophenyl)nitrenobenzamides. Comparison of the Energy Differences between Their Singlet and Quintet States Obtained Computationally and Experimentally
摘要:
The sign and magnitude of the intramolecular magnetic coupling between the two triplet nitrene units through the benzanilide chromophore have beep studied by temperature dependence of their EPR fine structures; The results that the interactions are ferromagnetic in the m,p' and m',p isomers and antiferromagnetic in the p,p' and m,m' isomers were corroborated by semiempirical CI calculations.

An object of the present invention is to provide a polyimide precursor composition solution that (i) uses no siloxane diamine, (ii) is curable at low temperature (not more than 250° C.) and (iii) has low viscosity regardless of its high concentration, and a photosensitive resin composition, photosensitive resin film, a thermosetting resin composition, a polyimide insulating film, and a printed wiring board with an insulating film, each of which has good physical properties and is obtained by use of the polyimide precursor composition solution. The foregoing object is attained by using a polyimide precursor composition solution which includes at least a (A) urethane imide oligomer having a terminal carboxylic acid group and a (B) diamino compound and/or isocyanate compound.
