POLYIMIDE PRECURSOR COMPOSITION AND PREPARATION METHOD AND USE THEREOF

The present invention provides a polyimide precursor composition comprising a polyimide precursor and a thermal base generator having the structure of formula (1): wherein R1, R2, R3, R4, R5 and are as defined in the specification. The present invention also provides a polyimide prepared from the aforementioned precursor composition, and a preparation method thereof.

BASE GENERATOR

The present invention provides a base generator having the structure of formula (1): wherein R1, R2, R3, R4, R5, and Y{circle around (?)} are defined as in the specification. The base generator of the present invention can be used for imidization of a polyimide precursor, promoting crosslinking of epoxy monomers, or crosslinking of polyurethane or polyurea.

Synthesis of peptidinol adenylates

Peptidinol adenylates were assembled by condensing the carboxyl group of N-blocked peptides with the alkylamino group of leucinol 5' adenosine phosphodiester. The latter was prepared as protected precursor from adenosine and leucinol by phosphite chemistry. The title compounds, which mimic aminoacyl adenylates, are designed to penetrate microorganisms via peptide permeases and to interfere with genetic translation.
