Intriguing Room Temperature Phosphorescence in Crystalline Porous Organic Frameworks

Abstract

Organic room temperature phosphorescence (RTP) materials have become a hot topic in the field of luminescence wherein the crystalline porous organic frameworks (metal–organic frameworks (MOFs), hydrogen‐bonded organic frameworks (HOFs), covalent organic frameworks (COFs))‐based RTP materials are receiving considerable attention. Beyond all doubt, crystalline porous organic frameworks‐based RTP materials perfectly integrate the advantages of crystalline porous organic frameworks and RTP materials. This review provides a timely and brief outline for the development of crystalline porous organic frameworks RTP materials including the construction strategy of MOFs/HOFs/COFs‐based RTP materials and their RTP performance as well as potential applications. Moreover, the conclusion and outlook are also discussed to present the challenges and prospects for further development of high‐performance MOFs/HOFs/COFs‐based RTP materials.

Crystalline porous organic salts

“…Essentially, the design for RTP materials revolves around two crucial factors: firstly, the facilitation of the intersystem crossing (ISC) process to achieve the triplet excited state; secondly, the effective mitigation of nonradiative transitions in the triplet state excitons. 110…”

Double-Model Decay Strategy Integrating Persistent Photogenic Radicaloids with Dynamic Circularly Polarized Doublet Radiance and Triplet Afterglow

“…Up to now, despite the significant progresses of acquiring colorful room-temperature phosphorescence (RTP) in organic phosphors, where the cocrystallization, , host–guest coassembly, , molecular polymerization, , supramolecular polymerization, , and metal–organic framework (MOF)/covalent organic framework (COF) incarceration − have been developed, the structural breakthroughs and mechanistic unveilings of colorfully emissive crystals with hybrid singlet, doublet, triplet excited states, and noninvasive stimulate manipulation are still an intriguing but challenging topic in the field of single-component organic room-temperature phosphorescence (ORTP), not to mention integrating color-tunable CPPL (Figure b) …”
