“…[1][2][3][4][5] The synchronous achievement of monochromaticity and multiwavelength switching is an essential requirement of miniaturized lasers for realizing more versatile integrated photonic elements. [6][7][8][9][10][11] Organic optofunctional materials, with abundant energy levels and excited-state processes, [12][13][14][15][16][17] provide an ideal platform to achieve multiwavelength switchable lasing.

Miniaturized lasers with multicolor output and high spectral purity are indispensable for various ultracompact photonic devices. Here, we propose an optically reconfigurable Förster resonance energy transfer (FRET) process to realize broadband switchable single-mode lasing based on in situ activation of acceptors. The stoichiometric ratio of the donor and acceptor in the ready-made microstructures could be modulated readily by precisely activating the acceptors through a photoisomerization process, leading to a reconstructed FRET process to achieve dynamically switchable lasing. Furthermore, dual-color switchable single-mode lasing was realized by selectively constructing the FRET process in an identical coupled microdisks system. These results advance a comprehensive understanding of excited-state dynamics in organic composite material systems, thereby providing new ideas for the rational design of miniaturized photonic materials and devices with desired performances.

“…Probe molecules in various biological systems, based on this mechanism, have also been suggested recently [ 10 , 11 ]. Moreover, ESIPT systems have found applicability in sensors for humidity [ 12 , 13 ], luminescent solar collectors [ 14 ], proton transfer lasers [ 15 , 16 , 17 , 18 , 19 ], photo stabilizers [ 20 ], devices based on thermally activated delayed fluorescence [ 21 , 22 ], white light generation [ 23 , 24 , 25 ], organic light-emitting diodes (WOLED) [ 26 ] as well as suitability in sensing of anion and cations [ 27 , 28 , 29 , 30 ], photochromic switching [ 31 , 32 ] and even understanding of fading of colorants in art [ 33 ].…”

In this short review, we attempt to unfold various aspects of excited-state intramolecular proton transfer (ESIPT) from the studies that are available up to date. Since Weller’s discovery of ESIPT in salicylic acid (SA) and its derivative methyl salicylate (MS), numerous studies have emerged on the topic and it has become an attractive field of research because of its manifold applications. Here, we discuss some critical aspects of ESIPT and tautomerization from the mechanistic viewpoint. We address excitation wavelength dependence, anti-Kasha ESIPT, fast and slow ESIPT, reversibility and irreversibility of ESIPT, hydrogen bonding and geometrical factors, excited-state double proton transfer (ESDPT), concerted and stepwise ESDPT.

White organic light‐emitting diodes (WOLEDs) have been regarded as the most promising candidate for full‐color display and solid‐state lighting applications owing to their favorable merits of high efficiency, superior white color balance, simple fabrication, and large‐area manufacturing possibility. Particularly, single‐emissive‐layer WOLEDs (SEL‐WOLEDs) with the reduced structural complexity, lower process cost, and feasible solution processing have drawn particular attentions. Numerous strategies have been proposed in recent years to construct SEL‐WOLEDs with improved device performance. This review focuses on the aspects, including: a) the molecular design methods for achieving a single‐molecule WOLED; b) the energy transfer mechanisms in various multiple‐molecule SEL‐WOLEDs with all‐fluorescence, all‐phosphorescence, and fluorescence‐phosphorescence hybrid structures; c) the combination of exciplex emitters and complementary fluorescent/thermally‐activated delayed fluorescent/phosphorescent emitters to realize SEL‐WOLEDs. Some future prospects on new opportunities and technological challenges in SEL‐WOLEDs are also covered.
