Utilizing d–pπ Bonds for Ultralong Organic Phosphorescence
Shuai Tian,Huili Ma,Xuan Wang,Anqi Lv,Huifang Shi,Yun Geng,Jie Li,Fushun Liang,Fushun Liang,Zhong-Min Su,Zhong-Min Su,Zhongfu An,Wei Huang,Wei Huang +13 more
TL;DR: Theoretical calculations and single-crystal analysis reveal that the d-pπ bond not only reduces the (n, π*) proportion of the T1 state, but also endows the rigid molecular environment with multiple intermolecular interactions, thus enabling long-lived phosphorescence.

Density‐functional thermochemistry. III. The role of exact exchange
TL;DR: In this article, a semi-empirical exchange correlation functional with local spin density, gradient, and exact exchange terms was proposed. But this functional performed significantly better than previous functionals with gradient corrections only, and fits experimental atomization energies with an impressively small average absolute deviation of 2.4 kcal/mol.

Development of the Colle-Salvetti correlation-energy formula into a functional of the electron density
TL;DR: Numerical calculations on a number of atoms, positive ions, and molecules, of both open- and closed-shell type, show that density-functional formulas for the correlation energy and correlation potential give correlation energies within a few percent.
