Published: June 4, 2024

Abstract Developing high‐performance polarization‐sensitive ultraviolet photodetectors is crucial for their application in military remote sensing, detection, bio‐inspired navigation, and machine vision. However, the significant absorption visible light range severely limits of photodetectors, such as high‐quality anti‐interference imaging. Here, based on a wide‐bandgap organic semiconductor single crystal (trans‐1,2‐bis(5‐phenyldithieno[2,3‐b:3′,2′‐d]thiophen‐2‐yl)ethene, BPTTE), solar‐blind with dichroic ratio close to 4.26 are demonstrated. The strong anisotropy 2D grown BPTTE crystals molecular vibration optical characterized by various techniques. Under voltage modulation, stable efficient detection polarized demonstrated, attributed intrinsic transition dipole moment bc plane, rather than other factors. Finally, high‐contrast polarimetric imaging successfully demonstrated highlighting potential semiconductors photodetectors.

Ambient‐Air‐Processed, Solution‐Based Organic Photovoltaics and Photodetectors

Advanced Optical Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 29, 2025

Abstract Organic photovoltaics (OPVs) and organic photodetectors (OPDs), which use conjugated polymers molecules as photoactive materials, hold significant promise for energy harvesting sensing applications due to their customizable optoelectronic properties, potential mechanical flexibility, compatibility with low‐cost, high‐throughput manufacturing. However, OPV OPD research date has typically relied on device fabrication in controlled environments (e.g., glove boxes filled inert gases) vacuum‐deposited (rather than solution‐processed) electrodes, limiting scalability increasing manufacturing complexity cost. This review explores these challenges by surveying the development of ambient‐air‐processed, solution‐based (APSB) OPVs OPDs, not only solution‐processed electrodes but are also entirely fabricated under ambient conditions. Various solution processing techniques, performance APSB OPDs comprehensively examined, offering insights future advance technologies toward ultra‐low‐cost optoelectronics harvesting.

A Fused Diketopyrrolopyrrole Derivative for Single‐Crystal Visible‐NIR Organic Phototransistor

Small Methods, Journal Year: 2025, Volume and Issue: unknown

Published: March 21, 2025

Organic phototransistors (OPTs) have garnered significant attention due to their potential in wearable and flexible electronics. However, achieving high carrier mobility broadband response organic semiconductors for OPTs remains a challenge. In this work, new fused diketopyrrolopyrrole (FDPP) derivative is reported, 2,9-bis(4-hexylphenyl)-7H,14H-thieno[3',2':7,8]indolizino[2,1-a]thieno[3,2-g]indolizine-7,14-dione (FDPP-p-C6), synthesized through N-cyclization of DPP with an adjacent thiophene unit. This ensures backbone planarity, while the hexyl side chains remain distant from core, minimizing steric hindrance promoting efficient intermolecular stacking. Consequently, single crystals FDPP-p-C6 exhibit planar typical herringbone packing arrangement, facilitating charge transport. The single-crystal field-effect transistors (OFETs) demonstrate p-type transport, maximum 0.20 cm2 V-¹ s-¹. Additionally, show promising performance, responsivity across broad spectral range photoresponsivity 2.2 × 103 A W-¹ along specific detectivity, derived noise current, 2.8 1010 Jones. study highlights FDPP as key material advancing OFET OPT technologies, propelling relevant research forward.
