TL;DR: In this paper, triplet photosensitization was used to demonstrate intramolecular singlet fission (iSF) with triplet yields approaching 200% per absorbed photon in a series of bipentacenes.
Journal ArticleDOI
Controlled preparation and properties of porous poly(l-lactide) obtained from a co-continuous blend of two biodegradable polymers
TL;DR: This study prepares porous PLLA from a blend of two biodegradable polymers based on a detailed and quantitative morphology control of the blends and indicates that this material also has potential as a substrate for controlled release applications.
Journal ArticleDOI

TL;DR: ASolid-state material formed from binary assembly of atomically precise molecular clusters able to interact electronically to produce a magnetically ordered phase at low temperature, akin to atoms in a solid-state compound is described.
Journal ArticleDOI
Molecular Clusters: Nanoscale Building Blocks for Solid-State Materials
TL;DR: This Account demonstrates how precisely controlling the structure and properties of nanoscale building blocks is key in developing the next generation of functional materials; several examples are discussed and detailed herein.
Journal ArticleDOI
Magnetic Order and Symmetry in the 2D Semiconductor CrSBr.
Kihong Lee,Avalon H. Dismukes,Evan J. Telford,Ren A Wiscons,Jue Wang,Xiaodong Xu,Colin Nuckolls,Cory Dean,Xavier Roy,Xiaoyang Zhu +9 more
TL;DR: CrSBr is established as an exciting 2D magnetic semiconductor and the SHG probe of magnetic symmetry to the monolayer limit is extended, opening the door to exploring the applications of magnetic-electronic coupling and the magnetic toroidal moment.
