Photocontrolled organic field-effect transistors (OFETs) containing a hybrid compound of fullerene C (n-semiconductor) with spiropyran (electrical conductivity photocontroller) as the active layer were fabricated for the first time. It was found that an OFET based on the hybrid compound, unlike the multilayer transistor (a device based on unmodified fullerene C and spiropyran in different layers), has higher transfer characteristics (source-to-drain current), charge carrier mobility in the active layer, and response rate to external influence, which makes them promising materials for the manufacture of optical memory elements.

Mimicking the superstructures and properties of spherical biological encapsulants such as viral capsids and ferritin offers viable pathways to understand their chiral assemblies and functional roles in living systems. However, stereospecific assembly of artificial polyhedra with mechanical properties and guest-binding attributes akin to biological encapsulants remains a formidable challenge. Here we report the stereospecific assembly of dynamic supramolecular snub cubes from 12 helical macrocycles, which are held together by 144 weak C-H hydrogen bonds.

Photocontrol over host frameworks is an elegant way to manipulate host-guest composites, yet the majority of previous systems suffer from long irradiation time and narrow guest scope, and are restricted to intramolecular photoreactions in organic solvents. Herein we present a photolockable polyaromatic capsule with high guest binding abilities in water. The capsule assembles from bent amphiphiles featuring two 2-subsutituted anthracene panels, which shows high stability against dilution and undergoes intermolecular [4+4] photo-oligomerization upon short light irradiation (<10 min).

The reversible photo-induced conformation transition of a single molecule with a [5]helicene backbone has garnered considerable interest in recent studies. Based on such a switching process, one can build molecular photo-driven switches for potential applications of nanoelectronics. But the achievement of high-performance reversible single-molecule photoswitches is still rare.

Programmable Persistent Room Temperature Phosphorescence Switches through Wavelength-Selective Photoactivation.

Angew Chem Int Ed Engl

State Key Laboratory of Organic Electronics and Information Displays & Jiangsu Key Laboratory for Biosensors, Institute of Advanced Materials (IAM) & Institute of Flexible Electronics (Future Technology), Nanjing University of Posts and Telecommunications (NUPT), 9 Wenyuan Road, Nanjing, 210023, P. R. China.

Controlling multicolor persistent room-temperature phosphorescence (RTP) through photoirradiation holds fundamental significance but remains a significant challenge. In this study, we engineered a wavelength-selective photoresponsive system utilizing the Förster resonance energy transfer strategy. This system integrates a photoactivated long-lived luminescent material as the energy donor with a fluorescent photoswitch as the energy acceptor, facilitating programmable persistent luminescence switches.

Controlling the packing of olefinic molecules in crystals is essential for triggering solid-state [2 + 2] photocycloaddition reactions and the synthesis of photocontrolled smart materials. Herein, we report the stepwise photodimerization-triggered photopolymerization of two triene coordination polymers (CPs), {[Zn(2-BBA)(tpeb)]·0.5CHCN} (, 2-HBBA = 2-bromobenzoic acid, tpeb = 1,3,5-tri-4-pyridyl-1,2-ethenylbenzene) and {[Zn(3-BBA)(tpeb)]·CHCN)} (, 3-HBBA = 3-bromobenzoic acid).
