Research Progress on CO2 Photocatalytic Reduction with Full Solar Spectral Responses
TL;DR: In this article, the discovery of photocatalysts that can convert CO2 into hydrocarbons is discussed. But, the authors do not consider the effects of CO2 emissions on the environment.

A cobalt mimochrome for photochemical hydrogen evolution from neutral water.
Emily H. Edwards,Jennifer M. Le,Alison Salamatian,Noelle L Peluso,Linda Leone,Angela Lombardi,Kara L. Bren +6 more
TL;DR: In this paper , a system for visible light-driven hydrogen production from water is reported, which makes use of a synthetic mini-enzyme known as a mimochrome (CoMC6*a) consisting of a cobalt deuteroporphyrin and two attached peptides as a catalyst, [Ru(bpy)3]2+ (bpy = 2,2′-bipyridine) as a photosensitizer, and ascorbic acid as a sacrificial electron donor.

Long-lived excited states of platinum(II)-porphyrins for co-catalyst-free solar-driven hydrogen evolution
Govardhana Babu Bodedla,Yue Dong,Geliang Tang,Jianzhang Zhao,Fuxiang Zhang,Xunjin Zhu,Wai Yeung Wong +6 more
TL;DR: In this article , two Pt(II)-porphyrins conjugated with naphthalimide (NI) chromophore, PtT(p-NI)PP and PtD(p)-NIPP, are synthesized in excellent yields and characterized by photophysical, electrochemical, and density functional theory studies.
Journal ArticleDOI
Origins of Molecular-Twist-Triggered Intersystem Crossing in Functional Perylenediimides: Singlet-Triplet Gap versus Spin-Orbit Coupling.
R. Ahmed,Arun K. Manna +1 more
TL;DR: In this article , the impact of molecular-twist on these energetics governing ISC is unveiled in a series of highly fluorescent prototype perylenediimides (PDIs) in dichloromethane implementing reliable quantum-chemical calculations.
Journal ArticleDOI
Tailoring intersystem crossing of perylenediimide through chalcogen-substitution at bay-position: A theoretical perspective.
R. Ahmed,Arun K. Manna +1 more
TL;DR: In this article , a few chalcogen (X = O, S, Se) bay-substituted PDIs (PDI-X2) are computationally modeled aiming at introducing geometrical-strain at the PDI core and also mixing nπ* orbital character to ππ* in the lowest singlet and triplet excited states, which altogether may reduce ΔES-T and also improve the SOC.

Light-harvesting fullerene dyads as organic triplet photosensitizers for triplet-triplet annihilation upconversions.
TL;DR: It is proposed that C(60)-organic chromophore dyads can be used as a general molecular structural motif for organic triplet photosensitizers, which can be use for photocatalysis, photodynamic therapy, and TTA upconversions.
