Polymorph-Dependent Electrogenerated Chemiluminescence of Low-Dimensional Organic Semiconductor Structures for Sensing

“…The main issue of organic micromaterials for the ECL application is the slow rate of charge transfer, which could result in the weak ECL signal for the sensors. Organic semiconductor micromaterials with large carrier mobility have recently attracted intensive attention in optoelectronics fields because of the unique size- and morphology-dependent optoelectronic properties, − which have been used as ECL sensors that have exhibited high sensitivity and stability. , For sensors with organic semiconductors as active materials, the performance of the sensors is dominated by both molecular structures and how organic molecules assemble themselves in the solid state. , When organic molecules are used as building blocks for construction of functional materials, their molecular-stacking arrangement and external crystal shape affect the optical and electrical characteristics of organic semiconductor materials, − which makes the materials a good platform for studying the structure–property relationship.…”

Novel Functionality of Organic 6,13-Pentacenequinone as a Photocatalyst for Hydrogen Production under Solar Light

“…47-2123). 29,30 In order to study the optical characteristics of the synthesized PQ, UV−visible absorbance (Figure 2) and PL spectra (Figure 3) were taken in chloroform. The UV−visible absorbance spectra showed the absorbance peak at 390 and 412 nm corresponding to the π−π* and n−π* transitions, and the band gap was observed to be around 3.17 to 3.0 eV, respectively.…”

“…The UV−visible absorbance spectra showed the absorbance peak at 390 and 412 nm corresponding to the π−π* and n−π* transitions, and the band gap was observed to be around 3.17 to 3.0 eV, respectively. 29,30 The peak at 300 nm was attributed to an aromatic ring.…”

“…The peaks at 408 and 432 nm are due to band edge emission of π−π* and n−π* transitions, respectively. 29,30 A FE-SEM image depicts the formation of platelike morphology (Figure 4). The length of the plates is in micrometers; however, the thickness of the plates is in the range of 50 to 70 nm.…”

“…The diffraction peaks at 9.8, 11.9, 14.7, 23.6, and 27.7° match (002), (011), (012), (112), and (104) reflection planes, respectively (JCPDS card no. 47-2123). , …”
