Charge-compensated zinc metallocenes of types [(η(3)-C(2)B(9)H(10))(2)Zn][(η(1)-NMe(2))ZnEt](2) (5) and [{η(3)-(Me)C(2)B(9)H(9)}(2)Zn][(η(1)-NMe(2))ZnEt](2) (6) were produced by reacting σ-/π-chelating aminoalkyl dicarbollides, 7-Me(2)N(H)CH(2)-7,8-C(2)B(9)H(11) (1) and 7-Me(2)N(H)CH(2)-8-Me-7,8-C(2)B(9)H(10) (2), with diethylzinc. Zincocene 5 proved to be an excellent synthon for the formation...

The relationship between molecular configuration and charge transfer processes in near-infrared-II (NIR-II) chromophores was studied, subsequently instructed the engineering of an efficient NIR photosensitizer (PS), as reported by Wenbo Hu, Yuliang Xiao et al. their Research Article (e202214875). resulting NIR-II PS not only enables image-guided vivo pulmonary coronavirus photo-ablation but als...

Two different hybrid cavitand-resorcin[4]arenes are shown to be effective and selective receptors for the molecular inclusion of positively charged organometallic sandwich complexes of appropriate size. The binding constants of the 1 : 1 complexes formed with a series of neutral and positively charged metallocenes have been calculated using different titration techniques. The motion of the incl...

The inherent constant-current electrolytic (CCE) nature of electrospray ionization mass spectrometry (ESIMS) is used to study a variety of neutral metallocenes, including oligomeric metallocenes. ESI mass spectra that display the doubly charged ion of certain biferrocenes (M2+) can be readily obtained by careful manipulation of solution conditions and structure of the biferrocene. The intensity...

The scope of applications of dialkyl dicyanofumarates and maleates as highly functionalized electron-deficient dipolarophiles, dienophiles and Michael acceptors is summarized. The importance for the studies on reaction mechanisms of cycloadditions is demonstrated. Multistep reactions with 1,2-diamines and β-aminoalcohols leading to diverse five- and six-membered heterocycles are discussed. Appl...
