“…Wang et al in 2019 synthesized four carbazole-based HTMs with variation in the numbers of triphenylamine (TPA) groups for PSC and studied the effect of altering the molecular structure of HTMs on photophysical and electrical properties. 98 The HTMs are coded as TPA 1 C (one armed) TPA 2 C (two armed), TPA 3 C (three armed), and TPA 4 C (four armed) Figure 10 were 141, 172, 189, and 203 °C, respectively, whereas TPA 4 C exhibited a high glass transition temperature which was more stable than that for spiro-OMeTAD (120 °C). Thus, from the thermal data it is evident that increasing the TPA unit does not only contribute to increasing the molecular weight of the glass transition temperature.…”

Solar cells constructed with organic−inorganic metal halide perovskite is a hot topic as they can replace the existing traditional silicon-based solar cells. The major hurdle in the commercialization of perovskite solar cells is the efficiency of the device. In this context, the use of a suitable organic hole transporting material would improve the efficiency of the perovskite solar cells. Until now, spiro-OMeTAD (2,2′,7,7′-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-spirobifluorene) is the standard hole transporting material (HTM) used in the fabrication of perovskite solar cells, and the major issue associated with spiro-OMeTAD is the complex multistep synthesis and the observed difficulty in the purification steps which make this HTM as cost-ineffective. Nowadays, certain hole transporting materials made up of organic small molecules carrying motifs like thiophene, triphenylamine, triazatruxane, pyrene, and carbazole exhibited better photovoltaic properties and less costs are involved for their synthesis, which motivate the researchers to work further on the design and development of non-spiro-OMeTAD. Among the various organic small molecule based HTMs, carbazole unit based HTMs exhibited better photovoltaic properties, chemical stability, easy functionalization, and device performance. Thus, the present review mainly focused on the diverse carbazole-based hole transporting molecular designs and their synthetic strategies which have been reported during the past eight years. Also, the review tries to correlate the molecular structure of different carbazole-based HTMs and their observed energy band gap, HOMO−LUMO levels, hole mobilities, and power conversion efficiencies for the fabricated perovskite solar cells.

Herein, a successive energy transfer (sEnT) strategy to enable a dehydrogenative 6π‐photocyclisation, without the need for an external oxidant is reported, in which the energetically unfavourable dehydrogenation is driven by energy transfer. The valuable applicability of this method was demonstrated by the scaffold hopping of indole containing bioactive molecules, as well as by the succinct synthesis of naturally occurring tetracyclic furocarbazole alkaloids. Moreover, experimental and computational studies were conducted to elucidate the reaction mechanism.

Severe greenhouse gas emissions have made global warming one of humanity's most critical and intricate environmental challenges. As the world's largest producer and exporter of steel, China's steel industry contributes substantially to carbon emissions. The government formulated the policies and pathways to achieve carbon neutrality, and enterprises have proactively pursued low‐carbon technologies. In this review, the decarbonization process in the Chinese steel industry is classified into three stages according to the decarbonization amount and technological maturity: the improvements of the blast furnace‐basic oxygen furnace, the attempt of the nonblast furnace, and the preparatory electricity‐hydrogen coupling metallurgy. This article reviewed the industrial‐scale low‐carbon metallurgical technologies represented by the Baowu HyCORF process, bottom‐blowing O2‐CO2‐pulverized lime converter process, gas‐based direct reduction shaft furnace process, Molong HIsmelt process, and Ouye furnace process, as well as pointed out the development limitations of those processes. Additionally, the study presented prospects for zero‐carbon emission technologies coupling green energy generation and hydrogen metallurgy. These findings will offer substantial support for advancing research and development of low‐carbon metallurgical technologies and formulating relevant policies in the future.
