Article Abstract
New classes of tridentate N-donor rhodium(I) complexes have been synthesized and demonstrated to exhibit interesting induced self-assembly behavior by variation of external stimuli, as a result of extensive Rh(I)···Rh(I) interactions, with the assistance of π-π stacking and hydrophobic-hydrophobic interactions. An isodesmic aggregation mechanism has also been identified in the temperature-dependent process. Upon aggregation in acetone solution, the complex molecules form wire-like nanostructures with their shape dependent on the π-conjugation of the tridentate ligands. On the other hand, crystalline needles of rhodium(I) complexes obtained from recrystallization have also been shown to exhibit conductivity on the order of 10(-3) S cm(-1).

The increasing prevalence of multidrug-resistant (MDR) bacteria, particularly , calls for the development of new antimicrobial agents. This study investigates a series of fluorinated azolium salts and their rhodium(I) complexes for antibacterial activity against clinical and reference strains of . : Eleven fluorinated azolium salts and their corresponding Rh(I) complexes (22 compounds total) were synthesized and tested against several strains, including three MDR clinical isolates (U-13685, H-9871, U-13815) and ATCC reference strains.

Phosphaalkenes are an underrepresented class of phosphorus-based ligands that hold great potential for the stabilisation of low-valent transition metal and main group fragments. We present the synthesis of a monoanionic PNP-type bis-phosphaalkene ligand and its reactions with [Rh(cod)(Cl)], which furnish two unique dinuclear Rh(I) complexes. These complexes show C-H activation of the Mes* groups of the PNP ligand and the presence of three different phosphaalkene coordination modes, respectively.

To study the role of hemilabile ligands in B─H bond activation, κ-N,E-chelated iridium and rhodium complexes, [Cp*M(κ-E-CHNE)(κ-N,E-CHNE)] (2a: M = Ir, E = S; 2b: M = Ir, E = Se; 2c: M = Rh, E = S; 2b: M = Rh, E = Se) have been synthesized by salt metathesis reactions of [Cp*MCl] (1a: M = Ir, 1a: M = Rh) and potassium salts of thio-/seleno-pyridine ligands. The strained four-membered rings in 2a-d indicate their potential for activating small molecules. Indeed, treatment of 2a-b with [BH⋅THF] afforded monometallic diborane(5) complexes, [(Cp*IrH){κ-B,B,Se-(BH-CHNE)}] (3a: E = S, 3b: E = Se) and transition metal (TM)-dihydroborate complexes, [(η-CMeH)Ir{κ-H,H,E-(HB-CHNE))] (4a: E = S, 4b: E = Se).

A new triaryl arsine (ArAs)-based metal-organic framework (MOF) named AsCM-102 has been prepared by the reaction of As(CH-4-COH) with Co(BF) and 4,4'-bipyridine. AsCM-102 contains pairs of staggered As donors that function as chelators for the facile incorporation of organometallic Rh species via a single crystal-to-single crystal transformation. Coordination of Rh is achieved by soaking crystals in a solution of [Rh(CO)Cl] at 70 °C.

Despite immunogenic cell death (ICD) has garnered significant attention in cancer therapy, achieving precise in vivo immunity activation and simultaneous visualization of immunotherapy processes remain significant challenges due to the difficulties in facile integration of multifunctionalities in a single nanomedicine. For this purpose, herein a self-adaptive rhodium(I) complex-based nanoplatform driven by metallophilic interactions is reported not only for near-infrared (NIR) imaging-guided cancer immunotherapy, but also as the first example of a rhodium(I)-based ICD inducer. Specifically, this nanoplatform enables high tumor enrichment by utilizing homologous targeting capability camouflaged by cancer cell membranes and facilitates enhanced in vivo NIR phosphorescence imaging.
