Abstract
![]()
In this study, two different classes
of push–pull chromophores
were synthesized in modest to excellent yields by formal [2+2] cycloaddition-retroelectrocyclization
(CA-RE) reactions. N-Methyl indole was introduced
as a new donor group to activate alkynes in the CA-RE transformations.
Depending on the side groups’ size and donor/acceptor characteristics, N-methyl indole-containing compounds exhibited λmax values ranging between 378 and 658 nm. The optoelectronic
properties of the reported D–A-type structures were studied
by UV/vis spectroscopy and computational studies. The complete regioselectivity
observed in the products was elaborated by one-dimensional (1D) and
two-dimensional (2D) NMR studies, and the electron donor strength
order of N-alkyl indole and triazene donor groups
was also established. The intramolecular charge-transfer characteristics
of the target push–pull chromophores were investigated by frontier
orbital depictions, electrostatic potential maps, and time-dependent
density functional theory calculations. Overall, the computational
and experimental results match each other. Integrating a new donor
group, N-alkyl indole, into the substrates used in
formal [2+2] cycloaddition-retroelectrocyclizations has significant
potential to overcome the limited donor-substituted substrate scope
problem of CA-RE reactions.

Abstract
A series of new push-pull chromophores were synthesized in moderate to very high yields (65%-97%) by treating TCNE and TCNQ with alkynes substituted by electron-rich diethylaniline and polycyclic aromatic hydrocarbons. Some of the chromophores exhibit strong intramolecular charge-transfer bands in the near-IR region with λmax values between 695 and 749 nm. With the help of experimental and theoretical analysis, it is concluded that the trend in λ max values is affected by PAH substituents sterically, not electronically. Steric constraints led to the increased dihedral angles, reducing conjugation efficiencies. The absorption properties of push-pull compounds have been investigated in solvents possessing different polarities. All chromophores exhibited positive solvatochromism. As an additional proof of efficient charge-transfer in push-pull chromophores, quinoid character (dr) values were predicted using calculated bond lengths. Remarkably, substantial dr values (0.045-0.049) were predicted for donor diethylaniline rings in all compounds. The effects of various polycyclic aromatic hydrocarbons on optical and nonlinear optical properties were also studied by computational methods. Several parameters, such as band gaps, Mulliken electronegativity, chemical hardness and softness, dipole moments, average polarizability, first hyperpolarizability, were predicted for chromophores at the B3LYP/6-31++G(d,p) level of theory. The predicted first hyperpolarizability β(tot) values vary between 198 to 538 × 10-30 esu for the reported push-pull chromophores in this study. The highest predicted β(tot) value in this study is 537.842 × 10-30 esu, 8150 times larger than the predicted β(tot) value of benchmark NLO material urea, suggests possible utilization of these chromophores in NLO devices. The charge-transfer character of the synthesized structures was further confirmed by HOMO-LUMO depictions and electrostatic potential maps.

Abstract
As a privileged structural motif, tetrahydroquinoline skeletons widely exist in biologically active natural products and pharmaceuticals. In this protocol, a highly diastereoselective [4 + 2] annulation of ortho-tosylaminophenyl-substituted p-QMs and cyanoalkenes to construct tetrahydroquinoline derivatives has been successfully achieved. This strategy proceeds efficiently under mild condition, offering straightforward route to a variety of 4-aryl-substituted tetrahydroquinolines with high yields, excellent diastereoselectivities, broad functional group tolerance as well as gram-scale capacity. Moreover, a one-pot reaction sequence utilizing in situ generated p-QMs under the similar condition to build tetrahydroquinoline framework is smoothly conducted with good reaction performance as well as step and atom economy.
