Key Points

To synthesize novel aromatic polyethers incorporating bis(porphyrin) perylenediimide triads into the main chain and evaluate their thermal behavior and photoresist utility.
Incorporated bis(porphyrin)-3,4:9,10-perylenetetracarboxydiimide triads as building blocks into the backbone of aromatic polyethers.
Characterized the thermal stability and determined the glass transition temperatures of the synthesized polyethers.
Formulated negative photoresists by combining the resulting unsaturated aromatic polyether with an anthrylsulfonium salt photoinitiator.
Successfully produced aromatic polyethers carrying bis(porphyrin) perylenediimide triad units along the primary polymer chain.
Observed elevated thermal stability evidenced by high glass transition temperatures in the resulting polyether materials.
Engineered viable negative photoresist systems using the unsaturated polymer matrix in combination with anthrylsulfonium salt.

Implication

Experimental study demonstrates high-temperature aromatic polyether synthesis in polymer systems, highlighting potential for negative photoresists.

Abstract

It was shown that aromatic polyethers (APs) containing in the main chain bis(porphyrin) perylenediimide triads as new building blocks can be obtained. Thermal properties of the prepared APs showing high glass transition temperature were studied. Negative photoresists based on the final unsaturated polymer and anthrylsulfonium salt were designed.
