A two-dimensional polymer from the anthracene dimer and triptycene motifs

R Bhola, P Payamyar, DJ Murray, B Kumar… - Journal of the …, 2013 - ACS Publications
A two-dimensional polymer (2DP) based on the dimerization of anthraceno groups
arranged in a triptycene motif is reported. A photoinduced polymerization is performed in the …

Dynamics of the triplet-pair state reveals the likely coexistence of coherent and incoherent singlet fission in crystalline hexacene

…, H Tamura, KW Williams, B Xu, Y Zhong, B Kumar… - Nature …, 2017 - nature.com
The absorption of a photon usually creates a singlet exciton (S 1 ) in molecular systems, but
in some cases S 1 may split into two triplets (2×T 1 ) in a process called singlet fission. …
