Balancing the second-harmonic generation (SHG) coefficient, band gap, and birefringence is a vital but addressable challenge for designing infrared nonlinear optical materials. By applying "rigidity–flexibility coupling" strategy, quaternary diamond-like phosphide, Mg2In3Si2P7, with wurtzite-type superstructure was successfully designed synthesized. Remarkably, it achieved rare coexistence of giant (2 × ZnGeP2 7.1 AgGaS2), suitable gap (2.21 eV), moderate (0.107), wide IR transparent range...
Ionic organic crystals containing planar π-conjugated units has become one of the hot spots as nonlinear optical (NLO) materials. However, although this type ionic NLO commonly have remarkable second harmonic generation (SHG) responses, they also suffer from overlarge birefringences and relatively small band gaps that be hardly beyond 6.2 eV. Herein, a flexible [C3 H(CH3 )O4 ]2- unit was theoretically revealed, showing great potential for designing with balanced properties. Accordingly,...

Abstract Polar materials play a crucial role in numerous essential fields; however, efficiently synthesizing them remains significant challenge. In this study, viable approach is proposed to enhance the probability of discovering polar by developing new functional basic units (FBUs) with strong polarity and high configurational entropy. To validate approach, site‐modification strategy applied entropy flexible (C 3 H 2 O 4 ) 2− FBU, resulting development four polar‐enhancing FBUs: (CH , F...
Polar molecular crystals, with their densely stacked polar nonlinear optical (NLO) active units, are favored for large second harmonic generation (SHG) responses and birefringence. However, potential practical applications as Infrared (IR) NLO materials has historically been underappreciated due to the weak inter-molecular interaction forces that may compromise physicochemical properties. In this study, we propose crystals cages a treasure-house development of superior IR representative...
Abstract Pnictides are superior infrared (IR) nonlinear optical (NLO) material candidates, but the exploration of NLO pnictides is still tardy due to lack rational design strategies. An in‐depth understanding structure–performance relationship urgent for designing novel and eminent pnictide materials. Herein, this work unravels a vital band gap mechanism pnictides, namely P atom with low coordination numbers (2 CN) will cause decrease delocalization non‐bonding electron pairs. Accordingly,...

Continuously, nitrides are mainly regarded as semiconductors or thermal conductivity materials and applied in photonic devices. In this work, we proposed that may also be a new system for mid-infrared (mid-IR) nonlinear optical (NLO) materials. Meanwhile, first report the halonitrides Zn2NX (X = Cl, Br) mid-IR NLO crystals, which were synthesized by solid–liquid reaction. Both compounds show excellent properties including large band gaps (3.21 3.28 eV), strong second-harmonic generation...
Unisexual taxa are commonly considered short-lived as the absence of meiotic recombination is supposed to accumulate deleterious mutations and hinder creation genetic diversity. However, gynogenetic gibel carp ( Carassius gibelio ) with high diversity wide ecological distribution has outlived its predicted extinction time a strict unisexual reproduction population. Unlike other vertebrates, males associated supernumerary microchromosomes have been observed in carp, which provides unique...
Unisexual lineages are commonly considered to be short-lived in the evolutionary process as accumulation of deleterious mutations stated by Muller’s ratchet. However, gynogenetic hexaploid gibel carp ( Carassius gibelio ) with existence over 0.5 million years has wider ecological distribution and higher genetic diversity than its sexual progenitors, which provides an ideal model investigate underlying mechanisms on countering ratchet unisexual taxa. Unlike other lineages, wild populations...
