Abstract: We report the preparation of poly(ionic) polymer-wrapped single-walled carbon nanotube dispersions for chemiresistive methane (CH4) sensors with improved humidity tolerance. Single-walled CNTs (SWCNTs) were noncovalently functionalized by poly(4-vinylpyridine) (P4VP) with varied amounts of a poly(ethylene glycol) (PEG) moiety bearing a Br and terminal azide group (Br-R1). The quaternization of P4VP with Br-R1 was performed using continuous flow chemistry and Bayesian optimization-guided reaction selection. Polymers (PyBrR1) with different degrees of functionalization were used to disperse SWCNTs and subsequently incorporated into sensors containing a platinum complex as an aerobic oxidative catalyst with a polyoxometalate (POM) redox mediator to facilitate room-temperature CH4 sensing. As the degree of quaternization in the PyBrR1-CNT composites increased, improvements in response magnitude were observed, with nominally 10% quaternized PyBrR1 giving the largest response. Incorporation of PEG improved sensor stability at relative humidities between 57?90% versus sensors fabricated from CNT dispersions with unfunctionalized P4VP. Devices fabricated with these dispersions outperformed those prepared in situ under dry conditions, and exhibited greater stability at elevated humidities. The influence of Keggin-type POM character was also evaluated to identify alternative POMs for enhanced sensor performance at high humidity. In an effort to identify areas for further improvement in algorithm performance for polymer functionalization, a kinetically informed machine learning model was explored as a route to predict reactivity of pyridine units and alkyl bromides under flow conditions.

Abstract: Metal-organic cages are often targeted for applications in which it is useful to tune the encapsulation of guest molecules inside a nanoporous environment. Modulating uptake and release of cargo from a host-guest complex usually requires control over the thermodynamic forces that favor association, and this control is commonly attained via addition of an external stimulus to interrupt the favorability of the inclusion complex. However, the stimuli used to alter guest binding often employ harsh conditions (eg, reducing or acidic conditions), so robust nanocages that can withstand these additives are of interest for investigating guest affinity. In this thesis, we present four related electroactive Pt 2+-porphyrinic nanocages that differ primarily in the capping substituents at the linkers and structure types (M 6 L 3 vs M 4 L 2). The incorporation of additional electroactive sites into the linkers of one cage increased its stability to reducing conditions relative to the cages without added redox activity. The affinity for anions to bind to the hosts was investigated using cages that differ only by the size of the cavity or the hydrogen-bond-donation ability of the linkers. The affinity for a host to bind strongly-or weakly-associating guests could be swapped via an acid stimulus. Redox stimuli could be used to form thermodynamically unfavored cation-in-cation complexes with two hosts, where metallocene cations bind in the reduced hosts and become trapped (for weeks to months) upon reoxidation of the host. Redox stimuli could also be used to tune the pK a of benzoic acid guests encapsulated in the metallated versions of one host. The presence and oxidation state of Lewis acidic metal centers in the porphyrin walls of a cage gave rise to ap K a swing of 12 units for the bound benzoic acid guest. The last chapter details common misconceptions found in interpretations of Frost diagrams and introduces means to clarify confusion surrounding these diagrams.

YieldReaction ConditionsOperation in experiment
In water; acetone; for 24h;Reflux; According to the flow scheme shown above, K2PtCl4 (tetrachloro platinum 1.2 equiv.) was dissolved in 1-2 mL of H20 and added to a solution of 4,4'-bisalkoxy-2,2'- bipyridine (1 equiv.) in acetone. The mixture was refluxed for 24 hours. A yellow solid precipitated out either under the refluxing conditions or upon cooling. Water was added to ensure complete precipitation of the [Pt(II)Cl2(4,4'-bis(RO)-2,2'-bipyridine)] product. Crude products were separated by vacuum filtration, and pure products were obtained by recrystallization or washing with the appropriate solvent.
