AI Article Synopsis
- The researchers designed hexakis(phenylethynyl)benzene derivatives featuring a tertiary amide on each blade to create a helical propeller structure through the interaction of point chirality.
- A hydrogen-bonding guest was captured by two amide groups, allowing neighboring blades to connect and form a supramolecular cyclic structure.
- The chiral group on the blades provided a means to control the helical bias, but it did not impact the overall dynamic helicity without the guest due to the flexibility of the blades.
Article Abstract
We designed hexakis(phenylethynyl)benzene derivatives with a tertiary amide group on each blade to achieve a helically biased propeller arrangement through the complexation-induced intramolecular transmission of point chirality. A hydrogen-bonding ditopic guest was captured at two amide groups, and thus could pair two neighboring blades to form a supramolecular cyclic structure, in which an auxiliary chiral group associated with a blade acted as a chiral handle to control the helical bias, while the chiral auxiliary did not exert any helical influence on the dynamic helicity in the absence of a guest due to the high flexibility of each blade.

Twisted intramolecular charge transfer (TICT) is a fluorescence quenching mechanism that occurs in donor-acceptor (D‒A) molecules. Chemical engineering research into TICT regulation over the past 50 years has primarily focused on manipulating steric factors by introducing alkyl groups at the D-A junction (pre-twisting). Herein, we report a significant advance in TICT-based probes through the introducing of H-bond as an efficient strategy for suppressing TICT.

Triazolated calix[4]semitubes comprising several binding sites were studied for complexation of Ag to get insight into the ability of the multitopic semi-tubular environment to host cation(s) in a structure-specific/switchable manner. For this purpose, a series of triazolated calix[4]semitubes having two or three 1,3-alternate calix[4]arene cores and crown-5-ether loops in the structures were prepared using the recently developed stepwise synthesis approach. Crown-5-ether loops were used as model receptor units which could be filled with K to charge positively either a specific 'end' or both 'ends' of the semi-tubular assemblies and to affect the complexation abilities of the internal binding sites of triazolated calix[4]semitubes.

We herein describe the comprehensive investigation of the complexation behavior of a guanidinium-modified calix[5]arene pentaisohexyl ether (GC5A) with a variety of typical luminescent dyes. Fluorescein, eosin Y, rose bengal, tetraphenylporphine sulfonate and sulfonated aluminum phthalocyanine were employed as classical aggregation-induced quenching dyes. 2-(-Toluidinyl)naphthalene-6-sulfonic acid and 1-anilinonaphthalene-8-sulfonic acid were selected as representatives of intramolecular charge-transfer dyes.

The push-pull molecules with an intramolecular charge transfer from donor to acceptor sides upon excitation exhibit a wide variety of biological and electronic activities, as exemplified by the in vivo fluorescence imaging probes for amyloid fibrils in the diagnosis and treatment of amyloid diseases. Interestingly, the structurally much simpler bis(4,8-disulfonato-1,5-naphtho)-32-crown-8 (DNC), in keen contrast to the conventional macrocyclic receptors, was found to dramatically enhance the fluorescence of twisted intramolecular charge-transfer molecules possessing various benzothiazolium and stilbazolium fluorophores upon complexation. Spectroscopic and microcalorimetric titrations jointly demonstrated the complex structures and the interactions that promote the extremely strong complexation, revealing that the binding affinity in these artificial host-guest pairs could reach up to a nearly 10(7) M(-1) order of magnitude in water, and the sandwich-type complexation is driven by electrostatic, hydrophobic, π-stacking, and hydrogen-bonding interactions.
