Dear @Ravi from your query, it is not clear what you're exactly asking for. Are you looking for methodological papers on Smart-PLS or the papers from different domains of research that have used Smart-PLS for data analysis?

paper treating sem pls as main subject of enquiry/ methods/statistical tool

(not social sciences subjects based applied research of psychology, hr, ob, mkt, mgmt)

@Ravi You can refer to the link below for the references you're looking for.

Thanks

Ravi Shankar Bhakat try to read these fundamental PLS references. Hopefully would help you not only for citations but for understanding as well.

As I have expertise in data analysis and exploring the underlying mechanism of PLS-SEM. I am suggesting you these books and articles to start reading and citing.

1) A Primer on Partial Least Squares Structural Equation Modeling (PLS-SEM).

2) Advanced Issues in Partial Least Squares Structural Equation Modeling.

3) When to use and how to report the results of PLS-SEM.

4) How to specify, estimate, and validate higher-order constructs in PLS-SEM.

Ravi Shankar Bhakat , if you use SmartPLS, it would also be fantastic if you cite the use of the software: https://www.smartpls.com/documentation/getting-started/cite This would be super nice support of that software development project.
