# Is there any way to tell Mathematica NOT to simplify an expression?

I have this expression:

Lx = (ℏ/I)*(-Sqrt[15/(8*π)])*(-Sin[ϕ]*(Cos[2*θ]*E^(I*ϕ)) -
Cos[ϕ]*Cot[θ]*(I*Cos[θ]*Sin[θ]*E^(I*ϕ)))


and I don't want Mathematica to do anything to simplify it. I want to see it as input in the exact way I've written it. How can I do this?
