Thermally Activated Delayed Fluorescence (TADF) materials have emerged as a revolutionary class of functional compounds, driven by their unique ability to utilize excitons from both singlet and triplet states for efficient fluorescence emission. This manuscript provides an overview of recent innovations in TADF material design, focusing on molecular strategies to achieve optimal TADF properties, including small singlet-triplet energy gaps (Δ ) and high photoluminescence quantum yields. We explore the diverse applications of TADF materials, spanning OLEDs, biomedical imaging, photosensitizers, photocatalysis, UV photodetectors (UVOPDs), electrogenerated chemiluminescence, triplet-triplet annihilation (TTA) sensitizers, organic hybrid microwire radial heterojunctions, multicolor luminescent micelles, mechano-luminescence (ML), light-emitting electrochemical cells (LEECs), and fluorescent probes.

Herein, a three-step general strategy featuring a thermal intramolecular Diels-Alder (IMDA) reaction to prepare the tricyclic 9-methyl-7-aryl-tetrahydro-6H-benzo[c]chromen-6-one core of morusalisin A is reported. This developed chemistry is applicable to the synthesis of a variety of tricycles, including 9-silyloxy and 9-phenyl-7-aryl-tetrahydro-6H-benzo[c]chromen-6-ones. In addition, a one-pot dehydration/IMDA procedure was demonstrated.

BsmI, a thermophilic Type IIS restriction endonuclease from Bacillus stearothermophilus, presents a unique structural composition, housing two distinct active sites within a single monomer. Recognition of the non-symmetrical 5'-GAATGC-3' sequence enables precise cleavage of the top and bottom DNA strands. Synthetic biology interventions have led to the transformation of BsmI into Nb.

ConspectusMetal-organic layers (MOLs), as a subclass of two-dimensional (2D) metal-organic frameworks (MOFs), have gained prominence in materials science by combining the structural versatility of MOFs with the unique physical and chemical properties of 2D materials. MOLs consist of metal oxide clusters connected by organic ligands, forming periodically extended 2D architectures with tunable properties and large surface areas. These characteristics endow MOLs with significant potential for applications in catalysis, sensing, energy storage, and biomedicine.

The single subunit RNA polymerases (ssRNAPs) of bacteriophages are highly interesting targets for the prediction and engineering of specific protein-DNA interactions. Despite extensive existing studies focusing on particular ssRNAPs such as the T7 RNAP, few rules governing the protein-DNA sequence covariations across diverse ssRNAPs and their cognate promoters are clearly known. Here, aiming to reveal such rules, we comprehensively mined promoters of various categories of ssRNAPs from phage genomes.
