Optical-limiting-based materials of mono-functional, multi-functional and supramolecular C60-containing polymers

TL;DR

This study investigates the nonlinear optical properties and optical limiting performance of various C60-containing polymer composites, revealing that certain functionalized fullerenes outperform C60 in limiting laser pulses at 532 nm.

Contribution

It introduces new C60-based composites and compares their optical limiting capabilities, highlighting improved performance of FCA/poly(styrene-co-4-vinylpyridine) over pure C60.

Findings

FCA/poly(styrene-co-4-vinylpyridine) exhibits superior optical limiting than C60.

Fullerenol and supramolecular C60 derivatives show weaker optical limiting responses.

The paper discusses potential reasons for performance differences among composites.

Abstract

By using nanosecond laser pulses at 532-nm wavelength, we have intensively studied the optical limiting and nonlinear optical properties of some new composites which consist of mono-functional 1,2-dihydro-1,2-methanofullerene[60]-61-carboxylic acid (FCA), multifunctional fullerenol, and supramolecular C60(HNC4H8NCH3)9 - containing polymers. The optical limiting performance of FCA/poly(styrene-co-4-vinylpyridine) is found to be better than that of its parent C60, while the multi-functional Fullerenol and supramolecular C60(HNC4H8NCH3)9 incorporated with polymers show poorer optical limiting responses. The possible sources for the improvement in the optical limiting are discussed.
