Published in 2025 at "Advanced Optical Materials"

DOI: 10.1002/adom.202501751

Abstract: The covalent linkages in covalent organic frameworks (COFs) extend π‐electron delocalization, providing an ideal platform for constructing materials with excellent third‐order nonlinear optical (NLO) properties. However, excessive π‐conjugation within COF planes leads to increased exciton… read more here.

DOI: 10.1002/cplu.202300094

Abstract: Here we report a second-order nonlinear optical (NLO) material [C(NH2)3]3C3N3S3 (GU3TMT), consisting of π-conjugated planar (C3N3S3)3- and triangular [C(NH2)3]+ groups. Interestingly, GU3TMT exhibits large NLO response (2.0 x KH2PO4) and moderate birefringence 0.067 at 550 nm, even though (C3N3S3)3- and [C(NH2)3]+ do not exhibit the most… read more here.

Published in 2017 at "European Journal of Organic Chemistry"

DOI: 10.1002/ejoc.201700094

Abstract: Several perylenediimide-based chromophores with peripheral benzanthrone groups were developed and characterized for their third-order nonlinear optics properties by using the femtosecond Z-scan technique. As a consequence, these chromophores were found to exhibit a moderate two-photon… read more here.
