Abstract Clusteroluminogens (CLgens), nonconjugated structures with visible luminescence at the clustering state, have recently received remarkable attention due to their great theoretical significance and practical values. In carbonyl‐based aliphatic polymers, ( n , π *) transition of carbonyl groups through‐space interactions been demonstrated play an important role in clusteroluminescence (CL) properties, but it is still a big challenge manipulate CL molecular level. this work, six...
Abstract Near-infrared luminophores have many advantages in advanced applications, especially for structures without π-conjugation aromatic rings. However, the fabrication of red clusteroluminogens from nonconjugated polymers is still a big challenge, let alone near-infrared clusteroluminogens. Here, we develop with full-spectrum blue to light (470 ~ 780 nm), based on color phenomenon polyesters synthesized amine-initiated copolymerization epoxides and cyclic anhydrides. We reveal that...

The length and mode of conjugation directly affect the molecular electronic structure, which has been extensively studied in through-bond (TBC) systems. Corresponding research greatly promotes development TBC-based luminophores. However, how through-space (TSC), one kind weak interaction, influence photophysical properties non-conjugated luminophores remains a relatively unexplored field. Here, we unveil non-linear relationship between TSC emission characteristics systems, contrast to...

Nowadays, electrochemiluminescence (ECL) efficiency of an organic emitter is closely related with its potential applications in food safety and environmental monitoring fields. In this work, 2,4,6-tris(4-carboxyphenyl)-1,3,5-triazine (TATB) was self-assembled to form hydrogen bond frameworks (HOFs), which worked as ideal reactors generate highly active oxygen-containing radicals, followed by linking isoluminol (ILu) via amide (termed ILu-HOFs). After covalent assembly aminated indium–tin...
Clusteroluminescence (CL) and through-space interactions (TSIs) of non-conjugated molecules have drawn more attention due to their unique photophysical behaviors that are different from largely conjugated luminogens. However, achieving red even near-infrared (NIR) emission such systems is still challenging the intrinsic drawbacks lack theories for structure-property relationships. In this work, six phenolic resins designed synthesized based on two molecule-engineering strategies: increasing...
The odd-even effect is a fantastic phenomenon in nature, which has been applied diverse fields such as organic self-assembled monolayers and liquid crystals. Currently, the origin of each remains elusive, all reported effects are related to ground-state properties. Here, we discover an excited-state through-space interaction (TSI) nonconjugated tetraphenylalkanes (TPAs). TPAs with even number alkyl carbon atoms (C2-TPA, C4-TPA, C6-TPA) show strong TSI, long-wavelength emission, high QY....
