Enhanced photoluminescence from group 14 metalloles in aggregated and solid solutions.

The unusual photoluminescence characteristics of a series of six group 14 metalloles (1,1-dimethyl-2,3,4,5-tetraphenylmetalloles and 1,1-diphenyl-2,3,4,5-tetraphenylmetalloles) containing silicon, germanium, or tin have been investigated. Although the compounds are weakly luminescent in dilute fluid solution at room temperature, they undergo a substantial enhancement of photoluminescence when forced to aggregate, as in mixed solvent systems. The compounds also exhibit considerable emission when incorporated into rigid room-temperature glasses of sucrose octaacetate. Absorption and emission characteristics of the compounds, including luminescence quantum yields, in fluid solution, solution-phase aggregates, and room-temperature glasses are reported. Quantum yields increase by as much as 2 orders of magnitude in the aggregates and glasses, compared to fluid solution. Experimental evidence supports the conclusion that the aggregation-induced enhancement of luminescence results from restricted intramolecular rotations in the packed metalloles. The unusual aggregation-induced enhancement of these compounds makes them potentially useful for the fabrication of a variety of electrooptical devices and sensors. In addition, the X-ray crystal structure of hexaphenylgermole is reported.

Assessing the compatibility of work system factors through an integrative model: a case study.

Work Factor Compatibility (WFC) theory proposes that human performance is dependent on the interaction of various components (e.g., physical and mental task demands, physical environment, social environment) of the work system and integrates multiple human performance perspectives into a single mathematical model. Work Factor Analysis (WFA) is a comprehensive survey administered to employees to determine the WFC index. WFA also provides recommendations for targeting specific work system areas for improvement. Preliminary testing of the tool was conducted at a manufacturing operation of a Fortune 10 company. Results are discussed and recommendations for further study are made.
