Controlled degradation of polymers by specific stimuli has attracted attention for a range of applications in which deliberate reduction of molecular weight is necessary. In photopatterning materials, chain scission effect has been actively explored to achieve highly improved modulation of the solubility as the solubility of the copolymer is inversely proportional to the chain length. However, the chemical designs have been largely changed from the conventional systems, leading to loss of advantages of conventional chemical units to patterning process. Herein, we discuss rationally designed molecular structures and chemical routes for realization of main chain scissionable polymer platforms which are compatible with monomers for two types of conventional photoresists, i.e. perfluorinated orthogonal photoresist and chemically amplified photoresist. The benefits of the main chain scission effect are further highlighted with the process to define pixels in organic light emitting diode device.
