None:
We report a concise five-step synthesis of the bis-BN-embedded dibenzoullazine (BNDBU) using a ring-closing metathesis/dehydrogenation sequence. A "fully" saturated species (f-BNDBU) and a "partially" saturated species (p-BNDBU) were also isolated during the dehydrogenation step. The photophysical properties of all three compounds were systematically investigated, and bulk heterojunction self-powered organic photodetectors based on BNDBU showed a competitive performance with an ultralow dark current density of 6.01 × 10-9 A cm-2 and a large on/off ratio of 5.89 × 104.

Structure of Benzene: Kekulé Model
He proposed that benzene has a cyclic structure of six carbon atoms attached to one hydrogen atom each, with three alternating pi bonds.
Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
