Formazans (Ar1-NH-NCR3-NN-Ar5), a class of nitrogen-rich and highly colored compounds,
have been known since the late 1800s and studied more closely since the early 1940s …

The second near-infrared (NIR-II, 1000–1700 nm) fluorescent probes have significant
advantages over visible or NIR-I (600–900 nm) imaging for both depth of penetration and …

The chromophores of several classes of well-established dyes, eg, indigo, 9, 10-
anthraquinones, formazanes, diketopyrrolopyrroles (DPPs), or certain azo compounds, are …

A boron difluoride formazanate dye that exhibits near‐infrared photoluminescence and
electrochemiluminescence was produced via a straightforward two‐step synthesis …

The rational design of a rigid π-extended ligand, suitable for the formation of four-coordinate
boron complexes, has led to the synthesis of the fused hexacyclic structure of carbazolo [2, 1 …

Bis (formazanate) iron (II) complexes undergo a thermally induced S= 0 to S= 2 spin
transition in solution. Here we present a study of how steric effects and π-stacking …

Luminescent organic semiconducting doublet-spin radicals are unique and emergent optical
materials because their fluorescent quantum yields (Φfl) are not compromised by the spin …

Synthesis, structure, and write once read many (WORM) type memory behavior of an ionic
organotin complex containing a 2-pyridine substituted formazan ligand is described herein …

The paper focuses on the synthesis of the chloro-, methyl and carbonyl derivatives of
Benzodioxole-BODIPY dye (BODIPY–4, 4-difluoro-4-bora-3a, 4a-diaza-s-indacene). Three …

We report conjugated polymers consisting of boron formazanate in the main chains. By
employing typical donor-type comonomers, such as fluorene and bithiophene, copolymers …
